Halo 4 server down?

hey, every time I try to play a game it says I’m not connected to the internet? I in fact am, as I am able to communicate within my Xbox live party. What’s going on?

I’m having the same issue currently, they fixed it in November but now in January it’s broken again, I think 343 needs to do a monthly reset on their server end to purge things like you would a router/modem. Once they did that it worked beautifully but they have to commit to this often
